@TheMuffinMan Well, the question isn't posted on Janitorial Supplies Stack Exchange, so that's a given, but you're also clearly underestimating importance of janitorial supplies in aerospace industry. Chuck Yeager used a broom handle as a makeshift lever so he could close the hatch of his X-1 after he broke two of his ribs. That broom handle enabled him to be the first man to break the sound barrier. Jack Parsons invented castable solid propellants as he observed two workers "mopping" the roofing asphalt on the roof of some storage building. Duct tape saved Apollo 13. And so on... —
